Dark Matter’s Not Enough Q&A

Why ‘invent’ dark matter rather than just adjust our understanding of the laws of gravity? Are there dark matter particles in orbit?
Following his lecture, Andrew Pontzen hosts a Q&A on the fantastically weird Universe.

The Universe seems to be governed by rules that we can, with some effort, understand. Andrew Pontzen introduces the stranger side of the cosmos – dark matter and dark energy – but then argues that these things are not so weird or unexpected after all. The strangest thing is that our rule-laden cosmos should be so predictable.

Andrew Pontzen is a lecturer and Royal Society University Research Fellow at University College London, as well as a musician and science communicator. His work focuses on galaxy formation and computational cosmology, as well as some early-Universe physics. Previously, he has held fellowships at Oxford Astrophysics and at the Kavli Institute for Cosmology in Cambridge. And now, he finds the time to go around the country presenting shows at science festivals.
